Abstract

The optical properties of the surface layers of amorphous Fe–Cr–B and polycrystalline Al–Si alloys modified by laser irradiation have been studied by spectroellipsometry. The laser irradiation changed optical conductivity of the surface layers of Fe–Cr–B and Al–Si samples significantly due to modification of their structure. Work deals with also effects of Ti+ and C+ ion-plasma mixed beam treatment onto optical properties of Mo and Ti surfaces in the infrared. The ion implantation of Ti sample changed the spectral dependence of its optical conductivity from the Drude-like to the Kaveh-Mott like one. It points to a stronger disordering of Ti compared to Mo sample.
